Answer:
58.8 Hz
Explanation:
The relationship between frequency and period of a wave is
![f=\frac{1}{T}](https://tex.z-dn.net/?f=f%3D%5Cfrac%7B1%7D%7BT%7D)
where
f is the frequency
T is the period
For the wave in this problem, we know its period:
T = 0.017 s
Therefore, its frequency is
![f=\frac{1}{0.017 s}=58.8 Hz](https://tex.z-dn.net/?f=f%3D%5Cfrac%7B1%7D%7B0.017%20s%7D%3D58.8%20Hz)
Answer:
the amount of each charge and the distance between them. ... Coulomb's law states the the electric force between two charges is proportional to the product of the two charges and inversally proportional to the square distance that separates their centers.
Answer:
Minimum percentage error = 20%
Explanation:
The zero error of the screw gauge is
(5*0.5)/50 = 0.05 mm
Least count on the circular scale is 0.5/50 = 0.01 mm
Equivalent circular scale reading = 0.01 * 25 = 0.25 mm
Reading on the main scale = 2 * 0.5 = 1 mm
Actual measurement = 1 +0.25-0.05 = 1.20 mm
The minimum percentage error in the reading will be (1.20 mm -1.00 mm)/1*100 = 20%
Answer:
a. absorbed
Explanation:
This is because for the internal energy of the sidewalk to increase, its temperature and thus its internal energy must increase. This causes it to heat up and this is done by absorbing energy from the UV wave.
I wasn't there observing the experiment while you and your class
performed it, so I don't really know how it was set up, or what
happened.
But I can tell you this: Light doesn't bend while passing through
any medium. It only bends at the boundary where one medium
meets a different one.
